‘SNL’ – Dylan McDermott or Dermot Mulroney?

Occasionally 'Saturday Night Live' offers up a sketch that isn't only clever in its dialogue but also in it's absurdity. Good example: last night's 'Dylan McDermott or Dermot Mulroney' skit, in which three guests — who refused to be introduced — appear on a game show in order to dechiper which actor is which.

As much as an SNL audience loves the absurd, they enjoy cameos even more so. Sure enough, one of these guys made an appearance on the episode. So which one was it... any guesses?
